Pitch Reclamation Project Colorado Mined Land Reclamation Board — 2016 Annual Reclamation Report <br /> 3.3 Constructed Marsh Areas in the Indian Drainage <br /> Reclamation related activities in 2016 consisted of continued monitoring of the improvements to the <br /> constructed marsh area near the location of the former Radium Treatment Plant (RTP) and the drainages <br /> above the Sediment Control Pond. The RTP was demolished and the area backfilled and recontoured in <br /> 2001, with final grading and initial revegetation in 2002. Reclamation activities have included graded the <br /> steep embankment behind the former RTP site to reduce the slope sluffing, and construction of a wetland <br /> area in the drainage to improved sedimentation control and to stabilize the slope adjacent to and down <br /> gradient from the RTP site. Activities have also included the development of marsh areas above the <br /> Sediment Control Pond by constructing small dikes in the drainages to allow the creation of small <br /> sedimentation basins, followed by the placement of timber slash in the drainage to retard flow velocity, and <br /> to trap sediment forming a wetlands type condition. Photograph 4 reflects the growth of cattails and sedges <br /> in 2016 near the former RTP site and Photograph 5 shows the marsh area above the Sediment Control <br /> Pond in 2016. <br /> 40 <br /> k- � _ � �-.t e - Mew,.. .y 'y s,.y;s '� Y., t_ A���`c' ,R `•� .-j�ti 4 -` - <br /> P <br /> � � 4 <br /> -�tr w_ s '•.� 1 .e�wt i � �' �. ra �\4 � {``Sks"x`� �_, i �� �,� <br /> �}».v'H6 ��`�tl+t'+'�'F', .t.►' �����'���'��\1��� ill,'.' � i� ��`�;+ �,i ` y ! \ � �t r V <br /> y . 1. 1sJu T <br /> NF al y" <br /> f(i <br /> 1, �l��j ���«�{1� �,,� fi 1i''�� ,y`' !i � ✓�� r 1 r! <br /> ;,�.,� <br /> '� <br /> f p i s i <br /> Photograph 4: Cattail and Sedge Growth in the Area of the Former RTP Site in 2016 <br /> 5 <br />
